WATER-GATE.

SPECIFICATION forming part of Letters Patent No. 660,356, dated October23, 1900.

Application filed June 14, 1900. serial No. 20,223. tllo modeLi To allwhom it may concern.-

Be it known that 1, CHARLES H. BAKER, a citizen of the United States,residing at Topia, Durango, Mexico, have invented an Improvement. inWater-Gates; and I hereby declare the following to be a full, clear, andexact description of the same.

My invention relates to an improvement in that class of gates which aredesigned to control the flow of water in pipes. v

It consists of a removable seat,with means for attaching it to thechamber, guides by which the gate is guided in its movements, andadjustments for the guides to retain the gate in contact with its seatafter the latter has been dressed down and its plane changed.

It also comprises asediment-chamber,with means for discharging it fromtime to time, so as to leave a clear space at all times for the movementof the gate, and details of construction which will be more fullyexplained by reference to the accompanying drawings, in which Figure lis a longitudinal section on the line 00 0c of Fig. 2. Fig. 2 is ahorizontal section on the line 2 z of Figs. 1 and 3. Fig. 3 is atransverse section on the line y y. Fig. leis a plan of the valve 3.Fig. 5 is a side elevation and plan of the guides. A

Water-gates are fitted to move in chambers transverse to the line ofpipe through which the water is flowing, and the face of the gate ismade to fit against a ground or otherwise fitted plane surfacesuliiciently tight to prevent the passage of the water when by means ofa wedge-shaped or inclined surface which provides a pressure to hold thegate firmly against the seat. Experience shows that the flow of water,especially that which is heavily charged with sediment of any kind, soonwears out the gate or seat and makes the joint leaky.

It is the object of my invention to provide means for removing the seat,so that it can be redressed and a new surface formed when it is wornout, which operation cannot be performed in the ordinary construction ofgates.

I have here illustrated one form of Watergate to which my invention isapplied. As shown, A is a section having the transverselyarrangedvalve-chamber 2, and this section low the threads on the gate-stem, andthus raise or depress the latter. The seat or face against which thegate closes is here shown as formed upon the end of a sleeve or section6, which is slidable into the gate-section A, and it is provided withflanges or bolts, so that it can be interposed between the gate-sectionand the next adjacent section of the conducting-pipe upon that side.This section 6 is fitted water-tight, and its inner end projects intothe valve-chamber 2, so as to be in line with the valve-face, which canbe thus closed against it. The valve -stem at is connected with the gateby means of a hollow housing or chamber 7, which projects from the backof the valve and has a vertical hole made into the top through which thevalve-stem passes.

The lower end of the stem is threaded andis adapted to fit the threadsof a nut 8, which is contained within the hollow housing, so that whenthe valve-stem has been securely locked with said nut it is incondition'to raise or lower the valve by the turning of the handwheel atthe upper end. Angular platesor braces 9 are cast or formed upon theback of the valve, extending from its periphery to the housing 7 andforming braces therefor.

In order to guide the valve in its movements, I have shown it formedwith vertical slides upon its opposite sides, as shown at 10, and theseslides are adapted to travel against the guides 11. These guides arefixed in place by nuts and supporting-bolts, as at 12, and the guideshave slots 13 extending horizontally outward from the bolt-holes, sothat the slides may be moved by loosening the nuts. The object of thisis to allow for adjustments of the valve-seat, which may take place fromtime to time by reason of its being dressed down after it has becomeworn and leaky. When this is done, the end of the seat-sec tion 6 willhave been removed a slight distance from the previous line of travel ofthe valve, and in order to bring the valve again c eedese into contactwith this seat it is necessary to' move it a distance corresponding withthe amount which has been dressed 0E from the seat. These guides 11allow of this adjustment by simply loosening the nuts and moving theguides forward until they press against the slide-surfaces 10 of thevalve, while the face of the valve travels in contact with its seat. Thevalve-stem may pass through an oval slot or opening in the top of thehousing 7, so that by loosening the nut 8 the valve can be moved towardthe seat, while the valvestem moving in the slot will retain its line oftravel and not be thrown out of adjustment by the movement of the valve.

In devices of this character it is often difficult to close the gate byreason of sediment collecting in the lower part of the valve-chamber. Asshown in my invention, the valvechamber has a concave depression 14 madein the lower part, and this has a screwthreaded nipple into which adischarge-pipe 15 is screwed. This discharge-pipe has a cook or valve,as at 16, and any sediment which is deposited at this point will fallinto the depression and the pipe may bedischarged from time to time byopening the cock.

By this construction of the valve'seat it is easy at any time to removeit from the gatesection, dress off the seat, and return it to its placewithout disturbing anything beyond the adjacent parts of the apparatus.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of a water-gate having a chamber and a valve-seattherein, of a valve to engage said seat, and guides for the valve saidguides adjustable to compensate for wear of the face of the valve.

2. The combination in a water-gate, of a gate-chamber, a section'formedtherewith adapted to connect with the adjacent pipeline, an independentseat-section, with means for securing it to the gate-section, with itsinner end forming a seat against which the gate is closable, verticalguides adjustably fixed in line with the back of the gate, andslide-surfaces formed upon the gate to travel against the guides.

3. The combination in a Water-gate of a chamber, a section formedtherewith adapted to be interposed in the line of the conductingpipe, anindependent removable section fitting into the gate-section having itsinner end adapted to form a seat for the gate, a gate having verticalslide-surfaces formed upon its opposite edges, guides against which thegate is slidable, said guides having horizontal slots and securing boltsand nuts whereby they may be advanced to maintain the gate in contactwith the seat.

4:. The combination in a water-gate of a chamber, a section formedtherewith, and means for securing it in the line of conducting-pipe,anindependent seat-section,a means for removably securing it to thegate-section, a box or housing formed on the back of the gate having aslotted opening for the reception of the valve-stem, and a not by whichthe latter is adjustably secured to the gate to allow the latter to beadvanced transversely, vertical slide-surfaces formed upon the back ofthe gate, transversely-adjustable guides over which said slide-surfacesare movable in the opening and closing of the gate.

5. The combination in a water-gate of a chamber, a section formedtherewith adapted to be interposed in the conducting-pipe, asupplemental removable seat-section fitting one end of the gate-section,a valve and means whereby it is movable transversely over the end of theseat-section to open and close, adjustable guides for the valve tocompensate for the wear of the valve-face, and a depression made in thelower part of the gate-chamber for the reception of sediment and a pipeand discharge-cock in line therewith.

In witness whereof I have hereunto set my hand.
